RAILROAD-RAIL FASTENING.

Specification of Letters Patent.

Patented Aug. 2, 1921.

Original application. filed August 5, 1919, Serial No. 315,471. Divided and this application filed November 18, 1919, Serial No. 338,830. Renewed February 23, 1921. Serial No. 447,225.

T 0 all whom it may concern:

a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Railroad- Rail Fastenings; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to means for fastening railroad rails to ties, sleepers, and the like, and for preventing creeping of the rails. The present application is a division of my application for railroad ties, filed August 5th, 1919, Serial No. 315,471, wherein a preferred form of sleeper or tie is shown, but

the present invention is not limited to any particular form of sleeper or tie per se.

The principal objects of the invention are (1) to provide novel means for fastening the rails to the sleepers, ties, girders, etc., whereon they may be mounted: (2) to provide novel means for preventing creeping of the rails in such fastenings: (3) to provide novel rail'fastening bolts: (4). to provide novel means for insulating the rail from its support; (5) to provide novel yokes for holding the rails: (6) to provide novel nuts for clamping the bolts.

The invention and the several subordinate novel features thereof will be hereinafter described, and embodiments thereof are illustrated in the accompanying drawings. I will describe the invention in detail as illustrated in the said drawings, and then summarize in the claims the essentials of the invention, and the novel elements, constructions, and combinations of parts for all of which protection is desired.

In said drawings: 7

F'gure l is a plan View of part of a sleeper, such as shown in by aforesaid application, showing a rail secured thereto by the novel fastening devices.

Fig. 2 is an enlarged cross sectional view on the line 22, Fig. 1.

Fig. 3 is a top plan View of Fig. 2;

Fig. 4 is a bottom plan view of Fig. 2.

Figs. 5 and 6 are respectively top and side views of one of the nuts detached.

' Figs. 7 8 and 9 are respectively top, side, and end views of one of the yokes detached.

As set forth in my aforesaid application each rail supporting-member or sleeper is preferably made of malleable iron and has an elongated oval base flange 1 extending entirely around it; the inner edge of this base flange being preferably upturned as at 1*. Above and extending across this base are transverse arched ribs 1, 1, 1 at each side of the center of the sleeper, the ends of each rib being merged into opposite side portions of the base flange 1 as shown in Fig. 1.

At each end of the sleeper and disposed on the longitudinal axial line thereof, is a seat 2, which is slightly wider than a rail, and is supported by and formed as an integral part of the end wall 1 of the sleeper and the adjacent transverse rib 1 The seat 2 is provided with upwardly projecting flanges 2 2 and with downwardly projecting flanges 2, 2 2 to strengthen it; and it may have openings 2 between the said flanges to lighten it.

At opposite sides of the transverse central line of the sleeper are second seats 3 in axial alinement with the seats 2. Each seat 3 is formed integral with and supported by the arched ribs 1, 1 and preferably has upstanding flanges 3, 3 and depending strengthening flanges 3, 3 3, as indicated in the drawings. Seats 3 may also have openings 3 corresponding to openings 2.

Each sleeper shown has four longitudinallyalined seats 2, 3; 3, 2 on its top.

Intermediate each pair of adjacent seats 2 and 3, at each end of the sleeper are oppositely inclined parts 5 formed integrally with and supported by the adjacent ribs 1 and 1; and provided with slots 5 for the passage of rail securing bolts, hereinafter referred to. The parts 5 may be strengthened by depending flanges 5 and 5 as indicated in Fig. 2. The slots 5 in adjacent parts 5 converge toward seat 2 and diverge toward seat 3, to enable rails having basesof different widths to be seated upon the seats 2 and 3 and secured by bolts passing through the slots 5 In order to deaden noise and insulate the metalof the rails from the metal of the sleepers blocks W of wood or insulating material are placed on the seats 2 and 3, and the rails are supported on such bloc rs.

Beneath each rail and between and above the parts 5 is a rail holding yoke 10 (see Figs. 2, 79) provided with clamping and anti-creeping lugs 1O adapted to be engaged with opposite sides of the base of the rail R and with openings 10 for the passage of bolts 11. The inner faces of the outer walls of these lugs 10 are beveled, as indicated at 1 in Fig. 7, so that when the yoke is turned across and engaged with the base of the rail the said beveled faces will bite ortend to bite into the edgeof the rail base and (when the yoke is fastened) effectively prevent creeping or longitudinal slip of the rail in either direction. i

The yoke 10 can be readily engaged with a rail b-yfirst placing it under and diagonally of the rail and then turning it so that the lugs 10 engage the flange of the rail, as shown, and when so engaged the yoke can'be slid under and along the rail until the openings 10 register with said slots. 25 7.

Then novel fastening bolts 11 are passed through the .openings 10 in the yoke and theslots 59in the parts 5 and engaged with nuts 15 placed beneath members 5.

Each bolt 11 preferably has a squared of the base of the rail and prevent creeping of the rails longitudinally, and bind the rails securely in position.

The nuts 15 are preferably provided on their upper sides with sockets 15 for the reception of blocks w of wood or insulating material, which are preferably set e dgewise andproject out of sockets 15 and above the top surfaces of the nuts, and engage the under sides of the parts 5, asshown in Fig.

2; When'the bolts 11 are tightened blocks to keep the nuts insulated from the metal parts 5. g 1 When the parts are properly'positioned, the bolt collarsjll engage the base of the rail R, and when the bolts are screwed" tightly into the nuts 15 the rail is securely held; while the blocks W and w and the clearance between the metal bolts 11 and theparts 5, effectually" insulate the rails fromthe metal sleeper or support.

. The sleepers shown are arranged l-ongitudinally of the track rails; and after they are properly positioned insulating blocks VJ are placed on the seats 2 and '3; thenthe rails It are positioned on such blocks; then yokes 10 are slipped under the rails and over the parts 5 and properly positioned. Then bolts 11 are slipped through the yokes and engaged with nuts 15; positioned beneath parts 5, and screwed down until thev heads 11 of the bolts engage the rail and firmly lockthesame, as indicated in Fig. 2.

The divergence of the slots 5 enables rails'of different'widths to be. readily securedto the sleeper by the same fastening devices. 7

With these novel rail fastenings tie plates, .such as have been heretofore used with wood ties, are dispensed with. The-yokes 10 also takethe place of the present so-called anticreepers and securely holdthe rails against creeping. This creeping is also prevented by the collars of the bolts, as above mentioned. V

While ,I have illustrated and described the invention as used to fasten rails to the: novel ties as set forth in my aforesaid application, the invention is not restricted to use with the particular sleeper shown and I the fastenings can be readily adapted and used to attach the rails to other forms of metal sleepers; bridge-girders; steel girders, wooden ties, etc, provided suitable provision is made therein for the engagement of the bolts.

the employment of divergent-slots, as these are useful principally in adapting the device for ready engagement with rails having bases of different widths. It is obvious that the invention as a whole, and the various subordinate.features thereof are capable of separate or combined use within the scope of the invention as set forth in the following claims. p
